Owing to the fact tois-pread laterally,

Having thus described the invention,what

I claim is exhaustmanifold and extended through the intake manifold,the conduit being made up of apluralityof separate pipes so grouped to form, within the intake manifold, a recess in the bottom of the conduit, the walls of the recess diverging downwardly and"laterally.j In testimony that I claim the" foregoing I have hereto aflixed signa-' 1- inssnn ro snAY as my own, ture.
